Overview

8mm | 24V | 120LEDs | 41.67cut | #7909-B | 1 SDCM Ultra-long LED strip light is part of the DENO 1 SDCM SMD Strips series, engineered around 1 SDCM LED strip. Key specifications: 2835, 120, 24V, 8 PCB, 3oz copper FPCB, cuttable 41.67mm. Every reel is produced on DENO's roll-to-roll line with 99.9% pure copper FPCB and ships CE, UL and RoHS compliant for architectural, retail and hospitality projects. OEM and ODM configurations of length, colour temperature and waterproofing are available on request.

Description

2835 1 SDCM long LED strip — 24V DC, 120 LEDs/m on an 8mm, 3 oz copper board, cuttable every 41.67mm, constant-current circuit. Buyer decision: every reel is binned inside a single MacAdam ellipse, so multiple 15 m (49 ft) single-feed or 30 m dual-feed runs match in colour across a whole project — no visible batch shift between rooms or floors. CC regulation keeps brightness uniform too. Custom CCT and IP — request a factory quote.

We use 99.99% gold wire, large-size chips, and thickened FPCB, backed by a 5-year warranty.

Applications

  • Cove, wall-wash & perimeter lighting — Coves, recesses, wall-wash details and ceiling perimeters where a continuous, uniform line of light is required.
  • Showroom & hospitality display lighting — Shelving, display cases, reception desks and signage backlighting in shops, showrooms and hospitality spaces.
  • Kitchen & wardrobe under-cabinet lighting — Kitchen, wardrobe and furniture task lighting where the strip stays hidden and only the light is seen.
  • Long corridor & warehouse runs — 48V feeding lets one run cover long corridors, warehouse aisles and facade lines with fewer injection points and fewer power supplies.

Frequently Asked Questions

What are the key specifications of 7909-B?

7909-B: 2835, 120, 24V, 8 PCB, 3oz copper FPCB, cuttable 41.67mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.

What colour temperatures and CRI options does this 1 SDCM LED strip offer?

This model is supplied as a 1 SDCM LED strip with high CRI options and the CCT range listed in the datasheet. DENO bins every batch for colour consistency, and custom CCT or spectrum combinations can be produced for project quantities.

Can DENO customise this 1 SDCM LED strip for a project?

Yes. DENO manufactures the 1 SDCM SMD Strips series as an OEM and ODM supplier: reel length, colour temperature, CRI grade, PCB width, waterproofing and private labelling can all be specified. Request a quote for lead time and project pricing.

What does 1 SDCM mean on a high CRI LED strip?

1 SDCM means every LED falls inside one MacAdam ellipse, so no visible colour difference exists between reels or between fixtures. Combined with Ra>90 and R9>50, this high CRI LED strip keeps white points matched across a whole project, which matters in retail, museum and hospitality installations where several runs sit side by side.

What limits how long an LED strip run can be?

Voltage drop and conductor current, not the LED itself. A long run LED strip combines low watts per metre, 2 oz or thicker copper and a higher bus voltage such as 24V, 36V or 48V to reach 20 m or more from one feed while staying inside a 3 percent drop.

Long LED Strip Lights — Buyer Questions

How long can a long LED strip run be on a single power feed?

A standard 24V constant-voltage tape is limited to about 5 m before the far end visibly dims. DENO's long-run boards combine 2 oz to 3 oz copper, 24V or 48V input and per-segment constant-current ICs, which takes a single feed to 20 m, and up to 50 m on 48V builds, with no measurable fall-off between the first and last metre.

What are the longest LED light strips DENO manufactures?

Standard reels ship at 5 m, 10 m, 15 m, 20 m and 30 m, and OEM orders are produced as one continuous 50 m board with no mid-reel solder joint. Roll-to-roll plating is what makes that possible: the copper is deposited continuously, so length is not capped by panel size the way it is on die-cut FPCB.

Do you supply extra long LED strip lights in 65.6 ft or 100 ft?

Yes. 65.6 ft (20 m) and 100 ft (30 m) are stock run lengths, and anything longer than 32 feet is supplied as one uncut board rather than two reels joined with a connector. Joints are the usual failure point on extra long LED strip lights, so removing them is the single biggest reliability gain on a large install.

Why do long strip lights get dimmer at the far end, and how is it fixed?

Copper resistance drops the supply voltage along the tape, so LEDs near the end of the run receive less drive current. Three fixes work together: raise the voltage (24V, 36V or 48V), raise the copper weight (2 oz or 3 oz), and add a linear constant-current IC per segment so each segment holds its current regardless of the local voltage it sees.

Which long outdoor LED strip lights are rated for wet locations?

Long outdoor LED strip lights are built IP65 silicone-coated, IP67 sleeved or IP68 fully potted, with DENO WAP™ conformal coating that stays clear instead of yellowing under UV. For facade and perimeter work the run length also has to survive thermal cycling, so outdoor boards use 3 oz copper and a wider PCB to spread heat.

What makes long lasting LED strip lights actually last?

Lifetime is decided by junction temperature and solder-joint fatigue, not by the LED bin. DENO specifies 99.9% pure electroplated copper for lower thermal resistance, gold-wire bonding, and derated drive current — L90 at 50,000 hours on standard architectural builds, backed by a 5-year warranty.

Can a long RGB or RGBIC strip run stay colour-consistent?

It can, provided each colour channel is current-regulated. On a plain long RGB LED strip the red die drops out first as voltage falls, so the far end shifts warm; a CC-regulated 24V colour board holds the mix over 15 m to 20 m. Addressable RGBIC runs additionally need data re-amplification roughly every 5 m.

Can long LED light strips be cut to an exact length for a room or kitchen?

Yes. Cut units run from 12.5 mm to 100 mm depending on voltage and density, so a run can be trimmed to a drawing dimension on site, and DENO also pre-cuts and pre-wires to length at the factory for room, cove and kitchen installations. Ask for the cut unit in the quote — it decides how closely the finished line matches the millwork.

Can you get LED strip lights longer than 32 feet in one run?

Yes — 32 feet (10 m) is where consumer tape stops, not where the physics stops. Past that the board needs constant-current regulation and 2 oz to 3 oz copper, and DENO supplies it as one uncut length with factory-fitted lead wires rather than two reels joined by a solderless connector, which would put the whole downstream current through a spring contact.

Should I specify a 65.6 ft or a 100 ft LED strip run?

65.6 ft (20 m) is the practical ceiling for a 24V constant-current board with 2 oz copper on a single-end feed, and it covers most cove and corridor jobs with one driver. 100 ft (30 m) moves to 36V or 48V with 3 oz copper, a bigger driver and usually a mid-point tap, because at 24V the current would be high enough for cable losses to matter.

When is a long RGBW LED strip better than RGB on a long run?

Whenever the same run also has to serve as everyday white light. Mixing white from three colour dies costs roughly twice the wattage for the same lux and renders skin and timber poorly — a real penalty over 20 m. RGBW adds a dedicated Ra 90+ white die at 2700K to 6500K, so white comes from a white source and the colour channels stay reserved for scenes.

1 SDCM LED Strip — Buyer Questions

What does 1 SDCM mean on an LED strip?

SDCM is the Standard Deviation of Colour Matching — the size of the MacAdam ellipse a batch's chromaticity falls inside. A 1 SDCM LED strip keeps every LED within one ellipse of the target point, which is below the threshold the human eye can resolve, so a wall wash reads as one continuous colour instead of a series of slightly different whites.

Will a re-order months later still match my installed 1 SDCM LED strip?

Yes, when the original batch reference is quoted on the purchase order. DENO archives the bin and reel data for each 1 SDCM build, so a replacement section or a phase-two extension is produced from the same bin instead of the current stock bin — the usual cause of a mismatched repair on architectural projects.
